Carnation named Stanblanca

ABSTRACT

A new variety of carnation plant having pale yellow blooms of medium size with a relatively large number of petals, the flowers being produced continuously and profusely on upright flower stems of good strength, the plant itself having a vigorous, upright growth habit with abundant production of foliage and characterized by its flowers being less susceptible to fusarium oxysporum.

BACKGROUND OF THE NEW PLANT

My new carnation variety was discovered by me in 1977 as a sport of the variety "Londorga" being grown for commercial purposes in greenhouse at Aalsmeer, The Netherlands, and this particular plant was selected for propagation and test because of its lovely pale yellow flowers of medium size and of excellent appearance because of the relatively large number of petals comprising each bloom. Propagation of this discovery plant was done by me by means of cuttings at Aalsmeer with very good results, which prompted me to carry on propagation in the same manner through several successive generations and over a period of several years, by which I found that the novel and distinctive characteristics of this new variety were fully retained from generation to generation and appeared to be firmly fixed.

DESCRIPTION OF THE DRAWING

My new variety of carnation plant is illustrated by the accompanying photographic drawing which shows, in full color, a three-quarter view of a mature bloom and partial face views of companion blooms, the entire drawing being intended to illustrate the nature of the blooms of this new plant. The color shown is as nearly true to that of the natural flower as herein specified as it is reasonably possible to obtain by conventional commercial photographic procedures.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of my new carnation plant based upon observations of greenhouse grown plants made at Aalsmeer, The Netherlands, in the summer of 1983, the color designations being according to The R.H.S.
